Problems solved by technology

[0002] Silicon PU court is an environmentally friendly court made by combining physical and chemical methods. It has good cushioning and ductility, and is easy to construct and maintain. However, the basic foaming of silicon PU courts has always been an unsolvable problem in the industry. Technical problems, especially in winter and spring, due to the low temperature and abundant rain, the basic maintenance period is very long, which seriously affects the construction period

Embodiment 1

[0036] (1) Basic treatment:

[0037] a. Grinding seam: Grind the base surface on both sides of the temperature joint with a width of 40-50 mm to a bevel depth of 3 mm, so that the surface of the temperature joint becomes a "V" shape, and the width of each side is 40-50 mm to improve the gap between the caulking glue and the base surface The bonding area increases its bonding force. The depth of 3mm is to ensure the thickness of the caulking glue without occupying the position of the elastic layer, to ensure the overall good cushioning, so that the thermal expansion and contraction of the foundation will not affect the surface of the silicon PU.

[0038] b. Pickling: Wet the foundation with clean water (to prevent dilute hydrochloric acid from penetrating into the foundation), evenly sprinkle and wash the base surface with dilute hydrochloric acid with a concentration of about 8%, and then rinse it with clean water, generally rinse twice, and ask for after washing and drying T...

Abstract

The invention provides a silicon PU court and a manufacturing method thereof. The court comprises a base plane, a primer layer coated on the base plane, an elastic layer positioned on the primer layer, a reinforcing layer coated on the elastic layer, a surface layer coated on the reinforcing layer, and at least one primer reinforcing layer arranged between the primer layer and the elastic layer. According to the invention, the reinforcing layer is added on the primer layer. With the cooperation of glass fiber mesh cloth and primer PU glue, the mesh cloth is applied on the surface of the base plane; with the high-strength tensile force of the fiber, the elastic layer bottom layer is not swelled due to water vapor rising of the base plane. Therefore, a base bubble problem of the silicon PU court is solved.

Description

technical field [0001] The invention relates to a silicon PU court and a manufacturing method thereof, in particular to a non-foaming silicon PU court and a manufacturing method thereof. Background technique [0002] Silicon PU court is an environmentally friendly court made by combining physical and chemical methods. It has good cushioning and ductility, and is easy to construct and maintain. However, the basic foaming of silicon PU courts has always been an unsolvable problem in the industry. Technical problems, especially in winter and spring due to the low temperature and abundant rain, resulted in a very long foundation maintenance period, which seriously affected the construction period. Under normal circumstances, the cement foundation often takes more than one month to dry completely, and it cannot be completely dry for two months in winter or spring. If the judgment is not accurate, small bubbles will still appear after the construction is completed. The more troubl...
